What is interpretative archaeology?

Interpretative Archaeology is one of the latest trends regarding Archaeological Theory (i.e. the way we view archaeological data, the methodology and theoretical background that affects our explanations and understanding... anyway it's complicated). Interpretativearchaeology is also known as Post-processual archaeology (i.e. Postmodern) but some might tend to separate them although boundaries between the two are vague. It is a trend that is "against" (actually) but also complementary to (as many leading archaeologists argue) to the previous trend, known as processual archaeology. It appeared in the late 80s - early 90s.
